Push yourself becaues no one else is going to do it for you.
The test contains a set of questions and there is no time limit. The test is not official, it's just one of the most efficient ways to see how much you know, or don't know, about the subject.Count your score
You will get 1 point for each correct answer. At the end of the Quiz, your total score will be displayed.Reflect on you answers
Please conduct a self review of your answers once you complete the quiz test. Being an active participant in your own evaluation, honestly assess your strengths and also areas you need to improve.

The key purposes of Terraform HCL include
- Infrastructure definition: Terraform HCL is used to define infrastructure resources such as servers, networks, and storage in a declarative manner.
- Resource dependencies: Terraform HCL allows users to define dependencies between resources, ensuring that they are created in the correct order and that changes to one resource don’t cause issues with other resources.
- Configuration management: Terraform HCL enables users to manage configuration parameters for resources in a consistent and repeatable manner.
- Version control: Terraform HCL files can be stored in version control systems, allowing users to track changes and collaborate on infrastructure code.
Overall, Terraform HCL provides users with a flexible and powerful tool for defining and managing infrastructure as code, making it easier to deploy and maintain infrastructure in a consistent and repeatable way.
